GM truck guys....2nd light harness for 5er?

**0rion** · 03-23-2011, 08:21 PM

I know there's a second wiring harness tied up between my bed and cab on my truck to run into the bed for a 5th wheel. Saw it today but didn't have time to pull it down and see what the end of it looks likes and what I'm gonna need to get it functional. I know there's a slot in the bed to run the wires through but is it as simple as just wiring it up to a 7 pin connector? Looks like I could see wire color labels on it.

Hope this helps:

Camper/Fifth-Wheel Trailer Wiring Package

The eight-wire camper harness is located under the front edge of the pickup box on the driver's side of the vehicle, attached to the frame bracket. A connector will have to be added to the wiring harness which connects to the camper.

The eight-wire harness contains the following camper/trailer circuits:

• Yellow: Left Stop/Turn Signal

• Dark Green: Right Stop/Turn Signal

• Brown: Taillamps

• White: Ground

• Light Green: Back-up Lamps

• Light Blue: Center High-Mounted Stoplamp (CHMSL)

• Red: Battery Feed

• Dark Blue: Trailer Brake

I don't want to cut into the bed to mount this thing....any ideas on how to mount the plug without cutting into the bed? I was thinking about building a box out of wood to mount it to and then putting that in the corner. I could just lay it in the bed but at some point it would get squashed and broken I would bet. Guess I could put some quick disconnects on there and take the whole plug off when I wasn't using it and zip the harness back under the truck.

I always just plugged in at the bumper. Some trailers may require re routing the wire. I'm not 7' tall so its way easier than climbing into the bed.

I've seen it mounted in the side of the bed just forward of where the tail light is....you can just reach over the bed and plug it in. It's more of a safety issue than anything. Really shouldn't be between the camper and truck. Not that I'm concerned about that too much.....I'd be more concerned with the wire flopping around and scratching up the back of the tail gate.
